WASHER DISTRIBUTOR.

Application filed October 9, 1923. Serial No. 687,564..

This invention relates to a machine for distributing washers. to the p1ns of heel molds and the like and is an improvement I of the washer distributing machine which forms the subject matter of my co-pending application Serial No. 667,565, filed October 9 1923.

M0lds for use in the manufacture of rubher heels and the like generally comprlse a base plate that has a series of washer receiving pins extending upwardly from the surface thereof, and upon which washers are positioned for subsequent lncorporation in the molded product I This invention contemplates an unprovement of my former device and provides a mechanism that will simultaneously position washers on a plurality of rows of such mold pins.

Fig. 5 is a vertical sectional view of the device shown in Fig. 4; Fig. 6 is a bottom plan view of a device shown in Fig. 4; and

Figs. 7, 8, 9 and 10 illustrate various phasesin the operation of the washer distributing units illustrated in Fig. 4..

The machine illustrated in Fig. 1 comprises a plane that is supported on a pair of spaced runners 1, and that has a deck 2 I on which a series of washer distributing units 3, 4 and 5 are respectively mounted on swingable arms 6, 7 and 8 that are held in a frame 9 that is formed integrally with the deck of the plane. A series of springs 10, 11 and 12 respectively extend from the washer distributing units 3, 4 and 5 to a corrugated spring supporting rod 13 which serves to resiliently align the respective dis- "tributing units with the direction of movement ofthe plane. A guide14 aligns the plane with the principal line of pins and the various elements 3, 4 and 5 are so related that they simultaneously follow adjacent rows of pins.

A handle 15 is attached to the rear portion of the deck 2 of the plane for convenience in pushing the plane over the surface of the mold that is adapted to receive washers from the distributing plane. The lowermost edges of the runners 1 are parallel, and jointly serve to definitely space the deck and therefore to position each of the distri buting units 3, 4 and 5, to operatively engage the mold pins. Each of the runners 1 is secured to the bed of the plane by means of a series of screws 16. The bracket 9, which constitutes a portion of the bed 2 of the plane, has a pair of uprights that are spanned by a of vertical pins 18 are rotatably mounted in adjustable sleeves 19. Each has a bearing 20 that is mounted in a suitable socket owned in the deck 2. The sleeve 19 is vertically adjustable in the yoke 17 by means 2 of the plane from the mold face yoke 17 on which a plurality of a threaded engagement therewith. A-

and 5 are mounted and by means of which the respective elements may be raised or lowered relative to the face of the mold.

The guide 14 that is secured to the front portion of the bed of the plane, is held in place by a tion it midway between the runners 1 of the plane.

of the units is illustrated in detail ing the distributing device over the inplurality of bolts 30 that POSl? Each of the distributing units 3, 4 and" 5 "is. of substantially identical structure. One in Figs.

- 4, 5 and 6 wherein the magazine portion 31 is e magazine 31 by means of constitute a guide for direct- I 7 opening 45 that is formed dividual pins upon which a washer is to be placed; For this reason the guides 35 have a flared: opening that .is ,sufiiciently large to engage any pin within the range of operation of its respective distributing unit. I The frame32 also has a pivot pin 36 extending'therethrough that supports a pivotally mounted member 37 that operates to release the washers one at a time through an aperture 38 thatis formed therein. The member 37 comprises a sleevethat is rigidly attached to the base portion and that has a supplemental spring seat 39 rigidly connected therewith. The parts 37 and 39 are rigidly assembled units that are separately constructed for convenience of manufacture. A spring 41 resiliently holds the member 39 into contact with the trailing portion 40 of the guide 35. The distributor sleeve 37 and the magazine portion 31 respectively have a Series of teeth 42 and 43 that cooperate to prevent dislodgment of washers from the stack that is supported within the magazine 31 during the operation of the device. A slot 44 is formed in the base portion of the distributor foot 37 of just sufiicient 'width to admit the head of a mold pin, and terminates at a point somewhat within the outer rim of the washers contained in the magazine 31 in substantially the same manner as in the corresponding element of my aforementioned copending application. The in the frame 32 serves as a means for anchoring the springs 10, 11 and 12, as the case may be, to the respective distributing device.

Additional structural details that are present in this form of washer distributing machine will be set forth during the description of .the operation of the machine.

Referring particularly to Figs 7, 8, 9 and 1O. the figures there shown represent a mold pin 46. that is rigidly mounted in a base plate 47, as moved across the sheet from left to right under the distributing device 3 in order to illustrate various phases of the operation of the distributing units.

The distributing device herein illustrated may either be moved over the series of mold the mold, together with the pins pins, or which it carries, may be moved under the distributing mechanism. For convenience of illustration, I have set forth the operation of my device by illustrating various phases in the movement of a mold pin underneath one of the distributing units;

The normal distances between the line of action of the distributors 3, 4 and 5 is approximately the same as the corresponding distance between the rows of mold pins. The distances between the distributors may V be adjusted to the proper value bv moving the springs 10 and 12 along the angle pin 13.

The pair of runners 1 position each of the distributing units 3, 4 and 5 a predetermined. distance above the face of the mold. This distance is determined by the approximate length of the mold ins. As the mold moves underneath the 'stributing unit the guide 14 engages a series of pins and aligns the direction of relative movement of the distributing plane with the central line of pins that is to be supplied with washers.

As the respective members 3, 4 and 5 approach the respective pins of the series over which the member is being moved, the uides 35 of each-of these devices engage t e respective mold pins which swings the corresponding distributing member 3, 4 and 5 directly over the in to which a washer is to be supplied. T e pin is thereby directed to the slot 44 that is formed in the base portion of the distributor foot 37 as indicated in Figs. 8 and 9 of the drawings.

As the mold pin a proaches the slot 44 it engages the pivota lymounted supporting foot 37 and raises the supporting foot a sufiicient degree to enable it to. ass over the to of the mtld pin. The distributor foot 3 carries the mold pin beyond the approaching edge of the lowermost washer 48 of the stack 49 that is carried by the magazine of the distributor unit. When the mold pin passes the edge of the slot 44, the distributor foot 37 dro s down over the head of the mold pin thereby. dropping a washer over the head of the mold pin and enabling the mold pin to engage the ap- I proaching edge'of the opening through the washer. This position is illustrated in Fig.

9 of the drawing. It will be noted that the mold pin iscarried slightly beyond the approaching edge of the washer by the base portion 37 of the distributor foot before the washer is dropped with its cone shaped portion uppermost. 7

Further movement of the mold pin causes it to engage the edge of the washer and to drag the washer 48 laterally throu h the aperture 38 from the stack 49 there ppsitiiig it upon the corresponding mold pin V e It will be noted that inthis operating sequence, the stack of washers is actually lifted and dropped over the top of the mold pin, thus insuring the absolute engagement of a washer with each mold pin. andtherefore reliability in' the operation of the device.

Since the remaining portions of the stack of washers 49 is again lifted bythis first slight movement of the lowermost washer y (la-- 48 during its removal from the stack, the

distribution of more than one washer to each mold pin is thereby precluded and, when the stack again dro s to its normal position as illustrated in Fig. 7 of the drawings, the remaining washers are positively held in the magazine. loss of washers upon the mold face is sub- The unintentional having pins of when straight washers without the conical form are used.

Although I have described a preferred embodiment of my invention, it obviously extends to other forms of distributing devices, and I desire therefore that only such limitationsshall be imposed thereon as are indicated by the spirit and scope of the appended claims.
